. My invention relatesto improvements vin index tabs and has, among its other objects the production of index tabs' of rthe kind' described' .which are simple, convenient, 'com-Y pact, durable, reliable, efcient, andjsatisfacof complete sets of index tabs, each tab lbeing 'individually complete and ready 'or ,iise,

thereby avoidingfthenecessity of removing thetab from a block ofsimilar tabs 0r oi' drawings, thel numeral l() generallydesig'fy nates a loose 4leaf ledger sheet or the like, upon Wliicli'my'improved tab is mounted. rlfhe tab Y f 65 tory forl use Whereverfound applicable.

A The invention contemplates the provision Vassembling fthe tab, or of the user taking other slips .toconiplete the tab, as isthe case with suchtabs as heretofore GolStlllCtQd "is preferably constructed" from Atvvo, sheetsV of A particular Vobject of the invention'is to providev indeX tabs of lthegkintil 'describedv Which are complete and ready for attachment to ledger leaves, card indexv leaves, and the leaves of loose leafbooks of variouskinds Without any preliminary assemblyA orvotvher steps preparatory to mounting.

To this end, my invention consists inthe "g y ,inV Fig. in '.perspeetivelin Fig. ,5, the Asheet being preferabiy'iormed symmetrical novel construction, `arrangement and combi.-l nation of parts herein shovvnV and described,

The sheet V11 is preferably made' symmetrical about "its longitudinal andfftransversef axes ,and .is

tially'shorter thanits length alongthe middle l folded portion",r therebyv producing a neat- "appearance and a saving of material.

The transparentA sheet 13 is shown in plan about itslongitudinal and Atransverse axesy with its middle edgeportionsconverging in- Wardly, thereby making the sheet relatively narrow along the 'l' transverse axial line of fold'. `The bounding edges ofthe middle portion ofthe sheet lmay beformedv as desired, but ,I prefer to use the iorm shown in'Fig. Y4,

'inasmuch as the sheet 1 8, when sov folded then takes Vthe shape shown in Fig''wherein kthe vprojectingzend portions 14 are connected by va folded tapering'stem 15. The sheet 11 hasa slot 16 out enit-s 'line of fold,'the lengthv ofthe slot being 'slightly in excess oftheV Widest portion ofthe steml, t

Cil

The tab is assembled by positioning the folded transparent sheet 18 within the sheet 11 with the stem 15 projecting through the slot 16 with the inner edges of the portions 14 contacting with the folded edge of the sheet 11, as best shown in Fig. 1. rlhe folded sheets 11 and 13, after assembly, are fastened together by a coating 17 of adhesive material on the inner face of the portions 11. The assembled sheets 11 and 13 are then secured to the leaf 10 in part by the adhesive coating 17 and in part by the uncovered portion of the adhesive material 12 on the inner faces of the sheet 11. The sheet 18 forms a substantially closed oval shaped memberV 18 Kor they may be numerals, the days of the month, abbreviations of the months, or in fact, anytl'iing desired. The pocket 20 formed inthe stem 15 is suitable to receive and hold strips 21 of different thicknesses by reason of the flexibility of the transparent material comprising the stems. i

In Fig. 6 I have shown the stem 15 as extending forward at an angle of substantially 45". By thus extending the tab forwardly the label is more easily read. The device shown in Fig. 6 is otherwise similar to that shown in Fig. 2, and the angle of inclination can be varied to suit the particular installation.

In Fig. 7 the tab is shown with the layers "forming the stem 15 in close contact, thereby omitting the pocket 2O which is provided in the other forms of the device to receive a strip 21 containing the'legend or characters. :The pocket 2() and strip 21 are dispensed with in this embodiment by stamping or embossing a Alegend or character on the material compris-- ing the stem 15. The stem 15, as thus arranged, can be extended forwardl 1 at an angle in the same way as the construction shown in Fig. 6.

It is obvious that the tab can be economically constructed and assembled ready for use by stamping the two main parts from sheets of material and pasting the parts together, thereby providing a complete assembled individual tab requiring no fastening means other than the adhesive material contained on the inner face of the sheet 11.A Each 0f the individual tabs equipped with a pocket 2O is suitable for havingany desired character or legend printed or otherwiseformed thereon. A supply of such stripsr of material ,containing a great variety of legends or characters most frequently used can be made available for use with tabs, or if desired, special labels can be made by typing or the like on strips of material of suitable size. In the embodiment of Fig. 7 where the stem 15 has the character stamped or. embossed on its outer surface this interchangeability is lacking, but such tabs possess the desirable features of permanency and the avoiding of the time and attention requisite for inserting label strips in the pocket 20. Thus it will be seen that I haveprovided an improved tab which is adapted to be economically manufactured and assembled and which is easily mounted onacard index leaf orthe like, asl desired. By keeping a supplyof the tabs and of the printedstrips of material on hand, the labor of indexing is minii'nized.V l Y IIaving thus described my invention, itis obviousy that various ,immaterial modificaverse axial line, oneof said strips having` a Ving' their inner faces coated with adhesive material, the folded'edge of said other strip taking substantially the form of a hollow cylinder.

In witness whereof,- I hereuntoV subscribe my name thisV 9th day. of December, A. D.
